Teenage cello virtuosos Emil and Dariel take the stage next. For their Top 12 shot, they've chosen a rock song, Aerosmith's "I Don't Want to Miss a Thing." Like Christian Soinev, they also have taken Howard Stern's advice, in their case to add a vocal chorus into the act. It's a splendid mix, with the cellos carrying the driving beat and lyrical melody, while the chorus floats on top, adding a dreamy layer to an already ethereal experience.
